that is the mp/hp levels. it is set to activate a hp pot at 30 and a mp pot at 20.
u must configure in the bot where do u have the pots in your client.
f.e., if, in the client u have the hp pot at the F2 key u must change in the bot the potion type of the F2 box to HP.
lets say that u have a bot char with 3000 hp / 900 mp leveling in norak2 and he was attacked a lot, hp is droping like crazy and he is using skills, when the health/mana (HP/MP) drops to 30 hp or 20 mp or less, the bot will activate a HP or MP pot to increase the hp/mp levels, but u can increase that number from 30 to XXXX (xxxx is ur full health)
